PROBLEM TO BE SOLVED: To provide an automotive hood panel made of fiber-reinforced plastic capable of certainly attaining requirement performance relative to the circumstance at collision accident. SOLUTION: In the automotive hood panel made of the fiber-reinforced plastic, an inner made of fiber-reinforced plastic for reinforcing an outer is joined to the outer made of fiber-reinforced plastic for forming an outer surface. The inner has a peripheral edge reinforcement part for surrounding an outer periphery along a peripheral edge of the outer and an inner part reinforcement part arranged so as to be connected to the peripheral edge reinforcement part at the inside surrounded by the peripheral edge reinforcement part. A ratio of length of a front part high rigidity area including a front part reinforcement part extending in a width direction at a vehicle body front part and length of a rear part high rigidity area including a rear part reinforcement part and an inner part reinforcement part extending in a width direction at a vehicle body rear part is 1.5 times or more. An inner bending introduction part extending in a width direction and having lower rigidity and/or strength than front and rear portions is formed on a side part reinforcement part for connecting the front part reinforcement part and the rear part reinforcement part at a specific position.
